Based on the image provided, this is not the normal healing process. It looks as though your dog has been licking excessively at the incision and flank, or has been too active after the surgery. However it is hard to tell exactly what is going on just based on a photo.
The sutures themselves take weeks to months to dissolve, depending on the suture type. It takes 1-2 weeks for the skin and the body wall to heal to a point where the sutures are no longer needed. Absorbable sutures should all be subcutanous (under the skin), so you should not be able to see them. If you can see them, that is a problem.
She needs to see a vet as soon as possible.
In some severe cases where the incision has become infected, she might need to go back to surgery to debride infected tissue and re-close the skin. At minimum she will likely need antibiotics and anti-inflammatories.
In the meantime, if you are not able to take her to a vet right away:
- Keep her rested, no rough play, only very short walks to toilet
- Put an e-collar on her to stop her from licking at the incision. If you do not have one, you can use an old t-shirt on her to try to prevent her from getting at the incision.
